Le leaderboard n'est que dans sa toute première version, et sera amené à évoluer régulièrement, avec de nouveaux jeux de données, de nouvelles métriques, et, nous l'espérons, beaucoup de nouveaux modèles ouverts soumis par la communauté ! Dans sa version initiale, nous avons couvert un panel de modèles ouverts, entraînés sur du français, de différentes tailles et origines. Note : les données d'évaluation ont été pour l'instant gardées confidentielles, pour préserver l'intégrité et la validité des résultats, et éviter les manipulations du classement.",
